Wooden rollercoasters are the trickiest jobs. They can't run with snow piled on the tracks. And if it doesn't melt, workers will have to climb the tracks and clear the snow by hand.

Park spokeswoman Elizabeth Gotway says it's a delicate operation.

"Some of our surfaces are very sensitive," said Gotway. "We can't just throw salt on our rollercoasters so we have to find another way to get it off. Certainly we are relying on Mother Nature to help us out after playing this trick on us. We're relying on her to give us a little warmer temperatures and sunshine."

Hints of sunshine did help melt some snow Tuesday afternoon. Gotway says the park will open as scheduled on Friday.
